Kyoko Tamada × ChronAir™
Handcrafted by Kyoko Tamada. One of a kind. Accompanied by an official ChronAir™ Provenance Certificate, recording the exact time and place its air was captured.
We accept orders for products starting from one unit. If you have specific requests regarding size, color, etc., we will contact you separately regarding feasibility and provide a quote.
Because each one is handmade, the size, number of bubbles, and the way the bubbles are incorporated will vary. No two are exactly alike.
A glass artwork that seals within it bubbles of CO₂ — each one recorded and verified for the very moment and place of its capture, in a form that resists any falsification. It holds a memory drawn from a single, unrepeatable moment, and — shaped bubble by bubble by hand — no two are ever alike: a singular, premium work of art.
As the world moves toward frameworks like the EU's Digital Product Passport, the ability to prove not just what a material is, but precisely when and where it originated, will become essential. This work is a first expression of that capability — beauty and proof, sealed together in glass.
Specifications
Product Name:
"The Great Wave" Paperweight
Product Number:
NAMI C001-BB
Size: Diameter approx. 6.5cm
Inside these bubbles is today's air — captured from one exact place and moment, and proven to be so.
"Weaving time, dyeing space" — this is how glass artist Kyoko Tamada describes her work. Inspired by Hokusai's Great Wave, this piece doesn't just show the sea — it holds its breath. And the air inside isn't the air of Hokusai's time. It's the air of now — this very moment of the world we live in, taken from one place, one instant, and kept here in the glass.
Two hundred years ago, Hokusai painted the power of nature. Today, the same wave carries a breath of the air around us — held still, resting in the palm of your hand. Not a picture of the world, but a small piece of it.
Specifications
Product Name:
"The Glow of the Air" Paperweight
Product Number:
Glow C001-UB
Size: Diameter approx. 6.5cm × H 8cm ＊Uranium glass
In daylight, a soft green glow. In the dark, under ultraviolet light, it comes alive — and the air sealed inside begins to shine.
This egg-shaped paperweight is made from uranium glass, a rare material that quietly fluoresces under ultraviolet light. Within it, countless delicate bubbles hold real atmospheric CO₂ — captured from a single place and moment of the air we breathe today, and sealed here in the glass.
By day, it rests like a small, luminous stone. But shine an ultraviolet light, and the whole piece awakens in a vivid green glow — as if the captured air itself were giving off light. A breath of our planet's atmosphere, held still, and quietly alive in your hands.
Specifications
Product Name:
"The Golden Hour" Paperweight
Product Number:
Gold C001-GB
Size: Diameter approx. 6.5cm
＊Contains gold leaf
The fleeting golden light of dusk — and a breath of that very air — held together in glass, forever.
There is a moment each day when the world turns to gold: the golden hour, just before the sun sets. This paperweight captures that feeling. Flakes of real gold leaf drift through the glass like the last light of evening, surrounded by delicate bubbles that hold real atmospheric CO₂ — captured from a single place and moment of the air we breathe today.
Gold has always been the color of permanence and light. Here, it surrounds a breath of our planet's atmosphere — a fleeting instant of air, made to last. A small, glowing world you can hold in the palm of your hand.

Memorial Edition
Memorial vr.
A one-of-a-kind commission — the air of your own chosen place and moment. CO₂ capture kit included. ChronAir™ Provenance Certificate included.
Some air belongs to no one but you. The morning a child arrived. The garden where two families became one. A corner café, a quiet distillery, a place only you would think to remember. With the included ChronAir™ capture kit, you choose the moment and the place — and that very breath of air is sealed within the glass, with a verified record of exactly when and where it was taken. Not our wave, nor the artist's studio, but your one moment in time — woven and dyed into glass, to last beyond a lifetime.

Premium Edition①
NAMI vr.
Limited edition of 100 pieces worldwide. Each comes with a serial number and ChronAir™ Provenance Certificate.
Two centuries ago, Katsushika Hokusai painted The Great Wave off Kanagawa, with Mount Fuji rising over the sea off Yokohama. Today, that same sea frames a modern skyline. Here, in the waters of Yokohama, we capture the air we seal within our works — bringing Hokusai's vision back to life as contemporary art, across two hundred years. The wave he saw and the air we breathe now meet in a single sphere of glass — one place, two centuries, held still in your hand.
(The CO₂ sealed in each work is captured at Osanbashi Pier, Yokohama. Image for illustration purposes.)

Premium Edition②
TAMADA vr.
Limited edition of 100 pieces worldwide. Each comes with a serial number and ChronAir™ Provenance Certificate.
Where the artist herself breathes. For four decades, in her studio Glass Flow, Kyoko Tamada has woven time and dyed space into glass — mono no aware, the quiet beauty of passing things, given form. The TAMADA vr. seals not a wave nor a distant view, but the very air in which her works are born. The photograph here is the studio itself — the same light, the same air that surrounds every piece she makes. A single breath drawn from the place of creation, held still and proven. The artist's own moment, sealed in glass, forever.
(The CO₂ sealed in each work is captured at the artist's studio, Glass Flow, Japan.)
